Reverting to a previous firmware version using the CLI

This procedure reverts the FortiGate unit to its factory default configuration and deletes IPS custom signatures, web content lists, email filtering lists, and changes to replacement messages.

Before beginning this procedure you can:

Back up the FortiGate unit system configuration using the command execute backup config.

Back up the IPS custom signatures using the command execute backup ipsuserdefsig

Back up web content and email filtering lists.

For information, see “Backing up and Restoring” on page 116.

If you are reverting to a previous FortiOS version (for example, reverting from FortiOS v2.80 to FortiOS v2.50), you might not be able to restore your previous configuration from the backup configuration file.

Note: Installing firmware replaces the current antivirus and attack definitions with the definitions included with the firmware release that you are installing. After you install new firmware, use the procedure “To update antivirus and attack definitions” on page 120 to make sure that antivirus and attack definitions are up to date. You can also use the CLI command execute update_now to update the antivirus and attack definitions.
